I created a bubble chart with numeric values on the y-axis and time(epoch) on the x-axis, and the bubble size is another numeric field.
I want to present the date value and not the epoch, so the users will understand the date. Is that possible?
Also, is there a way to add a line to the bubble chart (over the time), in order to show a trend?
Whats you search that you're currently using?
You cannot use a time as a Bubble or Scatter chart's X axis. This is not supported.
You would think it's just a big integer that you could fieldformat into whatever look you wanted, but that's not how it works. For those chart types they had to do some "special" handling of some things inside the code, and that special handling breaks times being used as the X axis.
(By the way, if you leave it as epoch it sort of, kind of works. It will be backwards and the scale will be ... umm ... "different", but it might be OK enough for your needs.)
After I reported a bug a while back for this inconsistent and baffling behavior, I got an answer:
After working with the Development team they have confirmed that currently plotting time axis on scatter chart is not supported.
(Along with various other information that informed me about the why).
But there's good news! If you have an active support contract, please create a P4 ticket (Enhancement Request) and refer to their internal Dev ticket "bug: SPL-152883". That will let them know there's more than one person who wants this to work right.
Now, MAYBE - ENTIRELY UNTESTED! - a workaround might be if you really want to use a bubble chart for a time-based X axis would be to ... like... maybe don't use dates or times, but build your own relative time in hours or minutes from start:
You could do this with something like (again untested)
... | eventstats min(time) AS earlyTime | eval myTime = _time - earlyTime then using myTime as your X axis field.
So, sorry about that bad news, but I hope we can find you a workaround!
Hi Rich thank you for your answer, it helped!
I understand that setting the x axis with time values is not possible, so I definitely take your solution.
